Specification'o'f Iletters Patentf Application filed Febru ary 8, 1913. Serial N0.-747 ,108.

T0 all 10h am it many concern Be it knowir that I, AnrnnoG; Hisooon, a citizen of theUnited States, and a resident of-Palatka, in the: county of Putnam and State of: Florida, have made certain new and usefulImprovements in Gombined Mufllers and Oil-Gas Producers of which: the followingiis a= specification.

My present invention relates to combined mufflers and oil gas producers, particularly adapted for connection within: the exhaust pipe" of internal combustion engine, my ob ectbelngi tor'puovide a snnple and 1neX- pensive C-OIlS't-THO'UQIY whereby the functlons generally presented in such a:device may be readily and effectively accomplish-ed.

@ther and further objects, and the advan tages= arising therefrom, will be apparent from the=following:description, in which referencciis in as to the *accoinp anying drawmg 1n 'wh1ch- 5 1 igure I is: a: central" longitudinal section througlr the device, illustrating the connections thereof in: diagram.- Flg; 2 1s an end view; Figi13 is detail transverse section taken th-erethrougln substantially on the line hollow and closed by ehd plates A and A theulatter of which pro vided 1 with a 1 centrali tube s,and thelformer of which is pro-v vided with a central tube a with a series of aperturesu extending around said tube. The outer portions of the tubes a and a are internally threaded fbnc'onnection with portions of the exhaust pipe ofl an: internal combustion engine (not shown). Th casing: A, is also provided with" an annular series of openings a" adjacent the end piece A, and against the inner surface of this end piece is disposed a rotatable valve disk C, having a circular series of apertures 0 whereby communication with the interior of the casing through the end openings a and the casing openings (4 may be controlled.

As seen particularly in Figs. 1 and 2, the casing end A is provided with a segmental slot a and a disk C is provided with a stud outstanding through the slot at and constituting a handle whereby the position of the valve disk may be readily changed.

Disposed within the casing A is a tubular core D, comprising a plurality of sections D, D and D and each of the sections is provided with outstanding flanges, certain of which are'indio'atcd by the letters (Z and are provided with a circular series of apertures d and a plurality of lugs (Z th :e

flanges being of such a size that the lugs extend liltO contact with the inner surface: of the casing. The other flanges iudicated at (Z are adapted to abutcertain of the flanges (Z. Extending through the core-6D 1s a tube E, theends of whichextend bd yond the end flanges (Z of the core and are externally threaded to receive the disks 6 which bear against said end flangesm The several abutting flanges d, cl and the end flanges (Z and: abutting disks 6 have their inner adjacent faces hollowed'out into sub stantially concavo convex formin order to provide annular chambers inwhich are disposed reticulated diaphragms- F which thus extend transversely of the core D and receive the tube E therethrough. The disk 6 therefore forces the several sections of the core tightly together and locks the same in position, gasket rings f being positioned be tween the contactingiportions ofthe several flanges and disks.

The core Dis provided with liquid fuel through i an intakepipe G, leading froma fuel supplypipe G" and provided with a controlling valve 9 therein. From thecore D; and adjacent relativelythe opposite end thereof from the inner pipe Gr leads an out let pipe- I-Twhich may have communication either with the engine pipe H or with a branch pipe- H entering into the casing A at oneend thereof, this communication be ing controlled vby a'three way valve H disposed the junction of the'sepipes; Thus instartingthe operation of the parts, and

I with the three-Way valveltl turned to con- ,nect the outlet pipe H with the branchpipe .Ilflthe valve disk 0 is positioned so as to register its openings 0 and 0 with the easing and the end openings a and (0 causing a continuous draft through the casing and the outer portion of the exhaust pipe, and liquid fuel is admitted through the intake pipe G by opening the valve 9. Thus the liquid fuel runs through the core D and through pipe H and branch pipe H into the casing A where the fuel is ignited by means of a torch or other instrumentality inserted through the draft openings and the subsequent combustion within the casing or cylinder heats the core D and accomplishes vaporization of the liquid fuel flowing therethrough. As soon as vaporization is started Patented Nov. 11,1913

the three-way valve H is turned to connect the outlet pipe H with the engine pipe H, thus cutting off the branch pipe H and permitting the vaporized fuel to pass to the engine. when the engine has been started its exhaust gases, outflowing through the exhaust pipe, enter the cylinder or casing A through the tube a and in consequence pass through the tube E and the apertures (Z of the several flanges (Z and thence outwardly through the tube a, the noise of the exhaust being muffled in such passage and the core D being maintained in a constantly hot condi tion so as to continue the vaporization of the liquid fuel.

It is to be understood that during the operation of the engine, the valve disk C is 7 turned to the position indicated in Fig. 2,

cutting off the supply of air to the casing or cylinder A and preventing the exhaust gases from escaping except through the natural outlet. From this it will be seen that the liquid fuel, upon entering the core D will be broken up by its passage through the dia phragms F between the intermediate flanges (Z and (Z and will therefore be in better condition for vaporization, it being understood that additional sections may be added on the core within a casing of greater length, and that the core may be taken apart if desired and the sections rearranged, in each instance bringing the diaphragms between the flanges (Z and disks e into action.

I claim:

1. In a device of the character described, a cylinder having apertures at one end and tubes extending from its opposite ends for connection with the exhaust pipe of an internal combustion engine, an apertured disk rotatable on the cylinder end adjacent the said apertures and adapted to control the same, a closed tubular core within said cylinder and having outstanding apertured and abutting flanges, the inner adjacent faces of which flanges are cut away to form com partments therebetween, reticulated dia Copies of this patent may be obtained for and adapted to permit of the passage of fluid from the outlet pipe through the engine and branch pipes as desired.

2. device of the character described comprising a cylinder having apertured ends and adapted for attachment with an engine exhaust pipe, a member forming a valve and controlling the apertures, a hollow closed core within the cylinder, apertured members extending bet-ween the core and the inner periphery of the cylinder whereby to form a muffler, valved engine connections extending outwardly from the core and having a branch pipe leading into the cylinder and a valved fuel inlet pipe leading into the core, all for the purpose described.

3. A device of the character described comprising a cylinder having apertured ends, a tube for attachment with an engine exhaust pipe, a member forming a valve and controlling the apertures of the cylinder, a hollow tubular core within the cylinder and comprising a plurality of sections having outstanding flanges, a tube extending through the core, disks removable on the tube to close the ends of the core and to hold the several sections thereof tightly together, valved engine connections leading outwardly from the core and having a branch pipe extending into the cylinder, and a valved fuel inlet pipe leading inwardly through the cylinder and into the core all for the purpose described.
